Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a guide structure for a moving handrail on a passenger conveyor.

0002

[Conventional technology]

So-called moving walkways, escalators, and other pedestrian conveyors are Install a handrail on the side or both sides, and place an endless moving handrail on this to create a moving bell. Generally, the structure is such that it moves in synchronization with the top or tread. By the way, that's it In the case of an escalator or a short moving walkway, a moving handrail such as the one shown in Figure 3 should be used. Therefore, even if the handrail 1 is slid directly on the guide rail 20, the total resistance will not be too large. Therefore, the tension of the moving handrail 1 does not increase, which causes problems in terms of drive and life. However, recently, the length of passenger conveyors has become longer, with lengths of 100 to 150 meters. As a result, moving handrail 1 also becomes longer, so moving handrail 1 and this guide become longer. The resistance between the moving guide rails 20 becomes considerably large, and as a result, the movement of the moving handrail 1 becomes difficult. As the power required increases, the tension also increases, while the strength of the moving handrail 1 itself increases. Since there is a limit to the improvement of the handrail, there is a problem that the lifespan of the moving handrail will be shortened. Ta.

0003 For this reason, conventionally, the guide rails that make up the movable handrail section have been Rollers are arranged at a pitch of 400 to 1000 mm in the direction, and the rollers are used to move handrails and plan. The sliding resistance between the inner rail and the inner rail has been reduced. As a sliding guide structure, a rail with vertical grooves 211 formed in the side wall as shown in Figs. 4 to 6 is used. An intermediate wall 210 forming the bottom of the vertical groove 211 is formed at the middle of the height direction of the guide 21. The wall 210 and the parapet mounting bracket 4 are connected with long mounting bolts 22, and the vertical groove 211 is A flat guide rail 23 with roller mounting holes 230 formed at the required pitch on the upper end surface. , and melt the bearing bracket 24 protruding into the vertical groove 211 into the roller mounting hole 230. The bearing bracket 24 supports the middle of the roller shaft 8a, and the roller mounting hole is The movable handrail 1 is slid by rollers 8, 8 whose outer periphery protrudes from 230. was. However, in such a structure, the guide rail 23 is placed on top of the rail guide 21. This rail guide 21 is installed in a shallow vertical groove 211 whose bottom is an intermediate wall 210 in the middle height direction. Since rollers 8 and 8 are arranged, rollers 8 and 8 are small in terms of outer diameter and strength. Therefore, the durability of the roller itself is poor and its lifespan is short. Moreover, the installation space for rollers 8 and 8 is narrow, so the guide rail If dust accumulates between the rail guide 23 and the rail guide 21, the rollers 8 and 8 will make abnormal noises in a short period of time. In many cases, the rotational condition deteriorates and the captain's As the handrail becomes longer, the guiding action on the moving handrail tends to lack smoothness, and the surface Troublesome inspections and repair/replacement work have increased, creating major maintenance and economical problems. Ta.

0004 Therefore, the present inventor proposed in Utility Model Application No. 51-159425 that the bottom part is U as shown in Fig. 7. The guide rail 2 is fixed onto the ballast trade 31 via the molding 30. We proposed a movable handrail guide structure in which rollers 8 are installed inside the guide rail 2. It was.

[0005] With this configuration, a large empty space can be created within the U-shaped frame of the guide rail 2. Therefore, a roller 8 with a large diameter and good strength and durability can be installed there. As a result, long moving handrails can be operated smoothly.

[0006]

[Problem that the invention attempts to solve]

However, in the above configuration, the installation of the guide rail 2 to the ballast trade 31 is difficult. Since the process is carried out through the It became.

[0007] The present invention was devised in view of the above-mentioned problems of the conventional technology, and is simple and cost effective. The purpose is to provide a moving handrail guide structure that can be installed at a relatively low cost. .

[0008]

[Means to solve the problem]

Therefore, the movable handrail guide structure of the present invention has curved upper sides and a U-shaped bottom. Insert the upper curved guide part of the guide rail into the curved part of the moving handrail, and , Insert a U-shaped roller bracket into the bottom U-shaped frame at a predetermined pitch. , deck board reinforced with reinforcing material on the back side, guide rail U-shaped bottom, and rollers. The U-shaped bottom of the bracket is integrated with the fixing means, and the inside of each roller bracket is It is characterized by a roller inserted into the cavity that comes into contact with the back of the moving handrail.

[0009]

[Effect]

As mentioned above, the guide rails are fixed directly on the deck board with fixing means, and the No unnecessary parts such as moldings are used. In addition, please provide guidance when fixing it. There is a roller bracket inside the frame on the rail side, and a reinforcement part on the back side of the deck board. The deck of the guide rail is It can be firmly fixed on the board.

【Example】

The embodiment of the present invention will be explained below with reference to the attached figure 1. 1 is a moving hand. 2 is a guide rail, and this guide rail 2 is designed with a hairline finish. Move the stainless steel plate by roll forming or press forming. Curved guide portions 21, 21 similar to the inner surface shape of the handrail 1 are provided at the top thereof, and A frame portion 25 having a substantially U-shaped cross section is formed downward from the curved guide portions 24, 24, and this U-shaped In the frame part 25 of FIG. Arrange them at the bottom 26 of the frame 25 at the required distance (400 to 1000 mm) from each other as shown in the figure. At the same time, it is fixed on the parapet mounting bracket 4 with T bolts and nuts 10, and is strongly attached to the back side. Place the stainless steel reinforcing member 51 in place on the joined deck board 5 with adhesive. , These roller brackets 3 and guide rails 2 are fixed using bolts and nuts 6. Tighten and fix it as one piece. and each U-shaped roller bracket. Insert the roller 8 that contacts the back side of the moving handrail 1 into the inner cavity 7 of 3, and Both ends of the shaft 8a are supported by the roller bracket 3.

[0011] In addition, a section steel 52 in the shape of four dovetail grooves is welded to the back side of the reinforcing plate 51. , the deck board 5 is attached to the parapet mounting bracket by the T-bolt 10 inserted into this dovetail groove. Fixed to 4. 11 is the interior panel, which is connected to the deck board 5 and the reinforcing plate via the elastic body 12 Fixed between 51.

0012 In this embodiment described above, there is a deep and large space within the U-shaped frame portion 25 of the guide rail 2. Therefore, use this space to install roller 8, which has a large outer diameter and strength. This makes it possible to reliably reduce the sliding resistance of long moving handrails. However, since the space where roller 8 is installed is large, it is difficult to enter. The rollers are less affected by dust, which significantly improves the durability of the rollers. It is possible to provide stable guide for moving handrails over a long period of time. Maintenance is extremely easy as troublesome work such as repairs and replacements can be reduced. In addition, it is possible to reduce repair costs by that much, and the guide rail 2 and deck By integrating the keyboard 5, it is possible to reduce costs, so it is a good choice for man. This is a highly effective design in practical use as a guide structure for moving handrails on conveyors. Ru.

[0013]

[Effect of the idea]

As detailed above, according to the configuration of the present invention, the guide rail having the structure as described above can be used. Because the U-shaped bottom is fixed directly onto the deck board, there is no need for excess molding etc. It eliminates the need for major parts, makes installation easier, and reduces costs. The bottom of the roller bracket and the reinforcing member are installed together on the fixing part to fix it. Therefore, it is possible to securely fix the guide rail on the deck board. Become.
